You are evaluating five phylogenetic trees generated from a single cladistics analysis. Tree A shows 21 evolutionary events (i.e. the evolution of a shared, derived trait), Tree B shows 7 events, Tree C shows 18 events, Tree D shows 10 events, and Tree E shows 9 events. Which tree is most likely the correct one? Group of answer choices Tree A Tree D Tree B Tree E Tree C
Tarsiers are one of the small species of primates generally found in tropical islands like Bohol, Philippines. Gibbons are small apes usually found in the forests of Southeast Asian regions.
